Use of quinoline derivatives for the protection of cultivated plants

ABSTRACT

The use of quinoline derivatives of the formula ##STR1## against the harmful effects of herbicidally active 2-[4-(5-chloro-3-fluoropyridin-2-yloxy)-phenoxy]-propionic acid derivatives.

This application is a continuation of application Ser. No. 829,600, filed Feb. 13, 1986, now abandoned.

The present invention relates to the use of quinoline derivatives for the protection of cultivated plants against the harmful effects of herbicidally active 2-[4-(5-chloro-3-fluoropyridin-2-yloxy)-phenoxy]-propionic acid derivatives, and to herbicidal compositions containing a combination of herbicide and a protecting quinoline derivative. The invention relates also to novel quinoline derivatives.

With the use of herbicides, such as with the use of the aforementioned propionic acid derivatives, the cultivated plants can to a considerable extent suffer damage, depending on such factors as for example the dosage of the herbicide used and the mode of application, variety or type of cultivated plant, nature of the soil and climatic conditions, for example: duration of exposure to light, temperature and rainfall. Severe damage can occur in particular when, in the course of crop rotation, the cropping of cultvated plants resistant to the herbicides is followed by the cultivation of other cultivated plants which have no resistance, or inadequate resistance, to the herbicides that have been used.

It is known from the European Patent Publication Nos. 86,750 and 94,349 that quinoline derivatives can be used to protect cultivated plants against the harmful effects of aggressive agricultural chemicals.

It has now been found that, surprisingly, a protection of cultivated plants against damage otherwised caused by herbicidally active 2-[4-(5-chloro-3-fluoropyridin-2-yloxy)phenoxy]-propionic acid derivatives can be provided by treatment of the cultivated plants or parts of these plants, or of soils intended for the cultivation of the cultivated plants, with a safener (antidote) selected from a group of quinoline derivatives. The herbicidal action against weeds and wild grasses is not rendered ineffective by the quinoline derivatives.

Quinoline derivatives which are suitable for protecting cultivated plants aganst the harmful effects of herbicidally active 2-[4-(5-fluoropyridin-2-yloxy)-phenoxy]propionic acid derivatives correspond to the formula I ##STR2## wherein

R¹, R² and R³ independently of one another are each hydrogen, halogen, nitro, cyano, C₁ -C₃ -alkyl or C₁ -C₃ -alkoxy,

R⁴, R⁵ and R⁶ independently of one another are each hydrogen, halogen or C₁ -C₃ -alkyl,

A is any one of the groups --CH₂ --, --CH₂ --CH₂ -- or --CH(CH₃)--, and

Z (a) is cyano or amidoxime, which can be acylated on the oxygen atom, or

(b) is a carboxyl group or a salt thereof, a mercaptocarbonyl group or a salt thereof, a carboxylic acid ester group, a carboxylic acid thiol ester group, an unsubstituted or substituted carboxylic acid amide group, a cyclised, unsubstituted or substituted derivative of a carboxylic acid amide group, or a carboxylic acid hydrazide group, or

A and Z together form an unsubstituted or substituted tetrahydrofuran-2-one ring;

with the inclusion of the acid addition salts and metal complexes thereof.

By amidoxime is meant the group --C(NH₂)═N--OH. The amidoxime can be acylated on the oxygen atom. Amidoximes acylated on the oxygen atom are those of the formula --C(NH₂)═N--O--CO--E, in which E is --R⁷, --OR⁸, --SR⁹ or --NR¹⁰ R¹¹, wherein R⁷ is C₁ -C₇ -alkyl, unsubstituted or substituted by halogen or C₁ -C₄ -alkoxy, or is C₃ -C₆ -cycloalkyl, C₂ -C₄ -alkenyl, phenyl which is unsubstituted or substituted by halogen, nitro or C₁ -C₃ -alkyl, benzyl which is unsubstituted or substituted by halogen, nitro or C₁ -C₃ -alkyl, or is a 5- or 6-membered heterocyclic ring which contains one or two hetero atoms from the group N, O and S, and which is unsubstituted or substituted by halogen; R⁸, R⁹ and R¹⁰ independently of one another are each C₁ -C₈ -alkyl which is unsubstituted or substituted by halogen, or are C₂ -C₄ -alkenyl, C₃ -C₆ -alkynyl, phenyl which is unsubstituted or substituted by halogen, C₁ -C₃ -alkyl, C₁ -C₃ -alkoxy, trifluoromethyl or nitro, or are benzyl which is unsubstituted or substituted by halogen or nitro; R¹¹ is hydrogen, C₁ -C₈ -alkyl or C₁ -C₃ -alkoxy, or R¹⁰ and R¹¹ together with the nitrogen atom to which they are bound are a 5- or 6-membered heterocycle that can contain a further hetero atom from the group N, O and S.

Heterocycles denoted by R⁸ can be saturated, partially saturated or unsaturated heterocycles, for example thiophene, furan, tetrahydrofuran and pyrimidine.

Heterocycles formed by R¹⁰ and R¹¹ together with the nitrogen atom to which they are linked are saturated, partially saturated or unsaturated heterocycles. Examples of such heterocycles are: pyrrolidine, pyrroline, pyrrole, imidazolidine, imidazoline, imidazole, piperazine, pyridine, pyrimidine, pyrazine, thiazine, oxazole, thiazole and, in particular, piperidine and morpholine.

Alkyl as constituent of the acylated amidoxime Z embraces, within the limits of the stated number of carbon atoms, all straight-chain and all branched chain alkyl groups.

C₃ -C₆ -Cycloalkyl denoted by R⁷ is cyclopropyl, cyclobutyl, cyclopentyl or cyclohexyl.

To be mentioned among the C₂ -C₄ -alkenyl or C₃ -C₆ -alkynyl groups, as constituents of the acylated amidoxime Z, are in particular: vinyl, allyl, 1-propenyl, methallyl and propargyl.

Applicable for Z as a carboxylic acid ester group or a carboxylic acid thiol ester group is a corresponding acid radical which is esterified for example by an unsubstituted or substituted aliphatic radical, or by a cycloaliphatic, aromatic or heterocyclic radical which is optionally bound by way of an aliphatic radical and which is unsubstituted or substituted.

A preferred carboxylic acid ester radical is the radical --COOR¹² and a preferred carboxylic acid thiol ester radical is the radical --COSR¹³, wherein R¹² and R¹³ have the following meanings: an unsubstituted or substituted alkyl, alkenyl, alkynyl, cycloalkyl, phenyl or naphthyl radical or an unsubstituted or substituted heterocyclic radical. The radicals --COOR¹² and --COSR¹³ also include the free acids, R¹² and R¹³ being hydrogen, and also the salts thereof, R¹² and R¹³ then being a cation. Suitable salt formers are in this case particularly metals and organic nitrogen bases, especially quaternary ammonium bases. Metals suitable for salt formation are alkaline-earth metals, such as magnesium or calcium, in particular however the alkali metals, such as lithium and especially potassium and sodium. Also suitable as salt formers are transition metals, for example iron, nickel, cobalt, copper, zinc, chromium and manganese. Examples of nitrogen bases suitable for forming salts are: primary, secondary or tertiary, aliphatic and aromatic amines which are optionally hydroxylated on the hydrocarbon radical, such as methylamine, ethylamine, propylamine, isopropylamine, the four isomeric butylamines, dimethylamine, diethylamine, dipropylamine, diisopropylamine, di-n-butylamine, pyrrolidine, piperidine, morpholine, trimethylamine, triethylamine, tripropylamine, quinuclidine, pyridine, quinoline and isoquinoline, as well as methanolamine, ethanolamine, propanolamine, dimethanolamine, diethanolamine and triethanolamine. Suitable nitrogen bases are also quaternary ammonium bases. Examples of quaternary ammonium bases are tetraalkylammonium cations in which the alkyl radicals independently of one another are straight-chain or branched-chain C₁ -C₆ -alkyl groups, such as the tetramethylammonium cation, the tetraethylammonium cation or the trimethylethylammonium cation, and also the trimethylbenzylammonium cation, the triethylbenzylammonium cation and the trimethyl-2-hydroxyethylammonium cation. Particularly preferred salt formers are the ammonium cation and trialkylammonium cations, in which the alkyl radicals independently of one another are straight-chain or branched-chain C₁ -C₆ -alkyl groups, especially C₁ -C₂ -alkyl groups, which are unsubstituted or substituted by a hydroxyl group, for example the trimethylammonium cation, the triethylammonium cation and the tri-(2-hydroxyethylene)-ammonium cation.

A carboxylic acid amide group denoted by Z is a corresponding amide radical which is unsubstituted or can be mono- or disubstituted on the nitrogen atom, or in which the nitrogen atom is a constituent of an unsubstituted or substituted heterocyclic radical. Substituents of the amide group are for example an unsubstituted or substituted aliphatic radical which is optionally bound by way of an oxygen atom, an unsubstituted or substituted cycloaliphatic, aromatic or heterocyclic radical which is optionally bound by way of an aliphatic radical, or an unsubstituted or mono- or disubstituted amino group.

A preferred carboxylic acid amide radical is the radical --CONR¹⁴ R¹⁵, wherein R¹⁴ is hydrogen, an unsubstituted or substituted alkyl, alkenyl, alkynyl, cycloalkyl, phenyl or naphthyl radical, an unsubstituted or substituted heterocyclic radical or an alkoxy radical, R¹⁵ is hydrogen, amino, mono- or disubstituted amino or an unsubstituted or substituted alkyl, alkenyl, cycloalkyl or phenyl radical, or R¹⁴ and R¹⁵ together with the nitrogen atom to which they are linked form an unsubstituted or substituted heterocyclic radical.

Substituents of the organic radicals R¹², R¹³, R¹⁴ and R¹⁵ are for example halogen, nitro, cyano, hydroxyl, alkyl, haloalkyl, alkoxy, which can be interrupted by one or more oxygen atoms, alkylthio, haloalkoxy, hydroxyalkoxy, which can be interrupted by one or more oxygen atoms, hydroxyalkylthio, alkoxycarbonyl, amino, alkylamino, dialkylamino, hydroxyalkylamino, di-(hydroxyalkyl)-amino, aminoalkylamino, cycloalkyl, unsubstituted or substituted phenyl, unsubstituted or substituted phenoxy or an unsubstituted or substituted heterocyclic radical.

By heterocyclic radicals as constituents of the carboxylic acid ester radical, of the carboxylic acid thiol ester radical and of the carboxylic acid amide radical are meant in particular 5- or 6-membered, saturated or unsaturated, unsubstituted or substituted monocyclic heterocycles having 1 to 3 hetero atoms from the group N, O and S, for example furan, tetrahydrofuran, tetrahydropyrane, tetrahydropyrimidine, pyridine, piperidine, morpholine and imidazole.

Cycloalkyl radicals as constituents of the carboxylic acid ester radicals, of the carboxylic acid thiol ester radical and of the carboxylic acid amide radical are especially those having 3 to 8, in particular 3 to 6, carbon atoms.

Aliphatic acyclic radicals present in the substituent Z as constituents of the carboxylic acid ester radical, of the carboxylic acid thiol ester radical and of the carboxylic acid amide radical can be straight-chain or branched-chain and advantageously contain up to a maximum of 18 carbon atoms. A smaller number of carbon atoms is frequently of advantage, especially in the case of combined substituents.

A cyclised derivative of a carboxylic acid amide group denoted by Z is in particular an unsubstituted or substituted oxazolin-2-yl radical, preferably an unsubstituted oxazolin-2-yl radical.

A and Z together can form an unsubstituted or substituted tetrahydrofuran-2-one ring, the unsubstituted tetrahydrofuran-2-one ring being preferred, especially the unsubstituted tetrahydrofuran-2-on-3-yl ring.

In the compounds of the formula I, halogen is fluorine, chlorine, bromine and iodine, particularly chlorine, bromine and iodine.

Salt formers for acid addition salts are organic and inorganic acids. Examples of organic acids are acetic acid, trichloroacetic acid, oxalic acid, benzensulfonic acid and methanesulfonic acid. Examples of inorganic acids are hydrochloric acid, hydrobromic acid, hydriodic acid, sulfuric acid, phosphoric acid, phosphorous acid and nitric acid.

Suitable metal-complex former are for example elements of the 3rd and 4th main group, such as aluminium, tin and lead, and also of the 1st to 8th subgroup, for example: chromium, manganese, iron, cobalt, nickel, zirconium, zinc, copper, silver and mercury. The subgroup elements of the 4th period are preferred.

When in the compounds of the formula I A is --CH(CH₃)-- and the radical Z contains an asymmetrical carbon atom, or A and Z together form a tetrahydrofuran-2-one ring, there exist optically isomeric compounds. Within the scope of the present invention, there are meant by the corresponding compounds of the formula I both the optically pure isomers and the isomeric mixtures.

Where the structure is not more precisely given with the presence of one or more asymmetrical carbon atoms, the isomeric mixture is always to be understood.

Particularly suitable for application according to the invention are compounds of the formula I in which R¹, R² R⁴, R⁵ and R⁶ are hydrogen, R³ is hydrogen or chlorine, and the radical --A--Z is a group --CH₂ --COOR¹⁶ or --CH(CH₃)--COOR¹⁶, wherein R¹⁶ is C₁ -C₁₂ -alkyl, C₃ -C₆ -alkenyl, phenyl-C₁ -C₄ -alkyl or phenoxy-C₁ -C₄ -alkyl.

These novel compounds are produced, in a manner known per se, from a 2-(5-chloroquinolin-8-yloxy)-acetic acid derivative and a suitable alcohol by esterification; or from 5-chloro-8-hydroxyquinoline and a suitable α-haloacetic acid ester in the presence of a base.

Y is a group --NR¹⁶ R¹⁷, --O--R¹⁸, --S--R¹⁸ or --O--N═CR¹⁹ R²⁰,

R¹⁶ and R¹⁷ independently of one another are each hydrogen, C₁ -C₈ -alkoxy, C₁ -C₈ -alkyl, phenyl or benzyl,

R¹⁶ and R¹⁷ together with nitrogen atom carrying them form a 5- or 6-membered saturated nitrogen heterocycle which can be interrupted by an oxygen or sulfur atom,

R¹⁸ is hydrogen or the equivalent of an alkali metal, alkaline-earth metal, copper or iron ion; or is a quaternary C₁ -C₄ -alkylammonium or C₁ -C₄ -hydroxyalkylammonium radical; a C₁ -C₉ -alkyl radical which is unsubstituted or mono- or polysubstituted by amino, halogen, hydroxyl, cyano, nitro, phenyl, C₁ -C₄ -alkoxy, polyethoxy having 2 to 6 ethylene oxide units, --COOR²¹, --COSR²¹, --CONH₂ --, --CON(C₁ -C₄ -alkoxy)-C₁ -C₄ -alkyl, --CO--N--di-C₁ -C₄ -alkyl, --CONH--C₁ -C₄ -alkyl, --N(C₁ -C₄ -alkoxy)-C₁ -C₄ -alkyl or di-C₁ -C₄ -alkylamino; or is a C₃ -C₉ -alkenyl radical which is unsubsituted or substituted by halogen or C₁ -C₄ -alkoxy; or is a C₃ -C₉ -alkynyl radical which is unsubstituted or substituted by halogen or C₁ -C₄ -alkoxy; or is C₃ -C₉ -cycloalkyl; or phenyl which is unsubstituted or substituted by cyano, C₁ -C₄ -alkyl, C₁ -C₄ -alkoxy, acetyl, --COOR²¹, COSR²¹, --CONH₂, --CON(C₁ -C₄ -alkoxy)-C₁ -C₄ -alkyl, --CO--N--di-C₁ -C₄ -alkyl or --CONH-C₁ -C₄ -alkyl,

R¹⁹ and R²⁰ independently of one another are each C₁ -C₄ -alkyl, or together form a 3- to 6-membered alkylene chain, and

R²¹ is hydrogen, C₁ -C₆ -alkyl, C₁ -C₆ -haloalkyl, C₂ -C₆ -alkoxyalkyl, C₃ -C₆ -alkenyl, C₃ -C₆ -haloalkenyl, C₃ -C₆ -alkynyl or C₃ -C₆ -haloalkynyl.

In the compounds of the formula II, halogen, as an indenpendent substituent, or as part of another substituent, such as haloalkyl, haloalkoxy, haloalkenyl or haloalkynyl, is fluorine, chlorine, bromine or iodine, with fluorine or chlorine being preferred.

Depending on the number of carbon atoms present, alkyl is methyl, ethyl, n-propyl or i-propyl, as well as the isomeric butyl, pentyl, hexyl, heptyl or octyl. The alkyl groups contained in the radicals alkoxy, alkoxyalkyl, haloalkyl or haloalkoxy have the same meanings. Alkyl groups having a low number of carbon atoms are preferred in each case. haloalkyl radicals, are: fluoromethyl, difluoromethyl, trifluoromethyl, chloromethyl, trichloromethyl, 2-fluoroethyl, 2,2,2-trifluoroethyl, 1,1,2,2-tetrafluoroethyl, perfluoroethyl, 2-chloroethyl, 2,2,2-trichloroethyl, 2-bromoethyl and 1,1,2,3,3,3-hexafluoropropyl.

Cycloalkyl denotes mono- and bi-cyclic saturated hydrocarbon ring systems, such as cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl, cyclooctyl, cyclononyl, bicyclo[4.3.0]nonyl, bicyclo[5.2.0]nonyl or bicyclo[2.2.2]octyl.

Particularly remarkable is the protective action of quinoline derivatives of the formula I against such herbicides of the formula II in which Y is the group --O--R¹⁸, --S--R¹⁸ or --O--N═CR¹⁹ R²⁰, wherein R¹⁸ is hydrogen, C₁ -C₄ -alkyl or C₃ -C₄ -alkynyl, or C₁ -C₄ -alkyl which is substituted by C₁ -C₄ -alkoxycarbonyl or di-C₁ -C₄ -alkylamino, and R¹⁹ and R²⁰ independently of one another are each C₁ -C₄ -alkyl, or R¹⁹ and R²⁰ together form a C₄ -C₇ -alkylene chain.

The weeds to be controlled can be both monocotyledonous and dicotyledonous.

Cultivated plants or parts of these plants to be protected are for example those mentioned in the foregoing. The cultivated areas concerned are those on which cultivated plants are already growing, or on which the seed of these plants has been sown, and also the soil intended for the growing of these cultivated plants.

The amount of antidote to be applied in proportion to the amount of herbicide depends largely upon the type of application. In the case of a field treatment, which is carried out either with the use of a tank mixture containing a combination of antidote and herbicide, or with a separate application of antidote and herbicide, the employed ratio of antidote to herbicide is as a rule from 1:100 to 10:1, preferably 1:20 to 1:1, and particularly 1:1. With seed dressing, however, the amounts of antidote required in proportion to the amounts of herbicide applied per hectare of cultivated land are much smaller

From the field treatment, 0.01 to 10 kg of antidote per hectare, preferably 0.05 to 0.5 kg of antidote per hectare, are as a rule applied. For seed dressing, there are generally used 0.01 to 10 g of antidote per kg of seed, preferably 0.05 to 2 g of antidote per kg of seed. When the antidote is applied in liquid form by seed soaking shortly before sowing, there are advantageously employed antidote solutions containing the active ingredient at a concentration of 1 to 10,000 ppm, preferably 100 to 1000 ppm.

For application, the compounds of the formula I, or combinations of compounds of the formula I with the herbicides to be antagonised, are advantageously used together with the auxiliaries customarily employed in formulation practice, and are thus processed, in a known manner, for example into the form of emulsion concentrates, brushable pastes, directly sprayable or dilutable solutions, diluted emulsions, wettable powders, soluble powders, dusts or granulates, and also encapsulations in for example polymeric substances. The application processes, such as spraying, atomising, dusting, scattering, brushing or pouring, and likewise the type of compositions to be used, are selected to suit the objectives to be achieved and the given conditions.

The formulations, that is to say, the compositions or preparations containing the active ingredient of the formula I, or a combination of active ingredient of the formula I and the herbicide to be antagonised, and optionally a solid or liquid additive, are produced in a known manner, for example by the intimate mixing and/or grinding of the active ingredients with extenders, such as with solvents, solid carriers and optionally surface active compounds (tensides).

Suitable solvents are: aromatic hydrocarbons, preferably the fractions C₈ to C₁₂, such as xylene mixtures or substituted naphthalenes, phthalic esters, such as dibutyl- or dioctylphthalate, aliphatic hydrocarbons, such as cyclohexane or paraffins, alcohols and glycols, as well as ethers and esters thereof, such as ethanol, ethylene glycol, ethylene glycol monomethyl or -ethyl ethers, ketones, such as cyclohexanone, strongly polar solvents, such as N-methyl-2-pyrrolidone, dimethyl sulfoxide or dimethylformamide, as well as optionally epoxidised vegetable oils, such as epoxidised coconut oil or soybean oil; or water.

The solid carriers used, for example for dusts and dispersible powers, are as a rule natural mineral fillers, such as calcite, talcum, kaolin, montmorillonite or attapulgite. In order to improve the physical properties, it is also possible to add highly dispersed silicic acid or highly dispersed absorbent polymers. Suitable granulated adsorptive carriers are porous types, for example pumice, ground brick, sepiolite or bentonite; and suitable nonsorbent carriers are materials such as calcite or sand. There can also be used a great number of pre-granulated materials of inorganic or organic nature, such as in particular dolomite or ground plant residues.

Suitable surface-active compounds are, depending on the nature of the active ingredient of the formula I to be formulated, and optionally also of the herbicide to be antagonised, nonionic, cationic and/or anionic tensides having good emulsifying, dispersing and wetting properties. By `tensides` are also meant mixtures of tensides.

Suitable anionic tensides are both so-called water-soluble soaps as well as water-soluble, synthetic, surface-active compounds.

Soaps which are applicable are the alkali metal, alkaline-earth metal or optionally substituted ammonium salts of higher fatty acids (C₁₀ -C₂₂), for example the Na or K salts of oleic or stearic acid, or of natural fatty acid mixtures, which can be obtained for example from coconut oil or tallow oil. Also to be mentioned are the fatty acid-methyl-taurine salts.

So-called synthetic tensides are however more frequently used, particularly fatty sulfonates, fatty sulfates, sulfonated benzimidazole derivatives or alkylarylsulfonates. The fatty sulfonates or sulfates are as a rule in the form of alkali metal, alkaline-earth metal or optionally substituted ammonium salts, and contain an alkyl group having 8 to 22 C atoms, `alkyl` including also the alkyl moiety of acyl groups, for example the Na or Ca salt of ligninsulfonic acid, of dodecylsulfuric acid ester or of a fatty alcohol sulfate mixture produced from natural fatty acids. Included among these are also the salts of sulfuric acid esters and sulfonic acids of fatty alcohol ethylene oxide adducts. The sulfonated benzimidazole derivatives preferably contain 2 sulfonic acid groups and a fatty acid group having 8-22 C atoms. Alkylarylsulfonates are for example the Na, Ca or triethanolamine salts of dodecylbenzenesulfonic acid, of dibutylnaphthalenesulfonic acid or of a naphthalenesulfonic acid-formaldehyde condensation product. Also suitable are corresponding phosphates, for example salts of the phosphoric ester of a p-nonylphenol-(4-14)-ethylene oxide adduct, or phospholipides.

Suitable nonionic tensides are in particular polyglycol ether derivatives of aliphatic or cycloaliphatic alcohols, saturated or unsaturated fatty acids and alkylphenols, which can contain 3 to 30 glycol ether groups and 8 to 20 carbon atoms in the (aliphatic) hydrocarbon radical and 6 to 18 carbon atoms in the alkyl moiety of the alkylphenols.

Further suitable nonionic tensides are the water-soluble polyethylene oxide adducts, which contain 20 to 250 ethylene glycol ether groups and 10 to 100 propylene glycol ether groups, with polypropylene glycol, ethylenediaminopolypropylene glycol and alkylpolypropylene glycol having 1 to 10 carbon atoms in the alkyl chain. The compounds mentioned usually contain 1 to 5 ethylene glycol units per propylene glycol unit. Examples of nonionic tensides which may be mentioned are: nonylphenolpolyethoxyethanols, castor oil polyglycol ethers, polypropylene/polyethylene oxide adducts, tributylphenoxypolyethoxyethanol, polyethylene glycol and octylphenoxypolyethoxyethanol. Suitable also are fatty acid esters of polyoxyethylenesorbitan, such as polyoxyethylenesorbitan-trioleate.

In the case of the cationic tensides, they are in particular quaternary ammonium salts which contain as N-substituents as least one alkyl group having 8 to 22 C atoms and, as further substituents, lower, optionally halogenated alkyl, benzyl or lower hydroxyalkyl groups. The salts are preferably in the form of halides, methyl sulfates or ethyl sulfates, for example stearyltrimethylammonium chloride or benzyldi(2-chloroethyl)ethylammonium bromide.

The tensides customarily used in formulation practice are described, inter alia, in the following publications:

"Mc Cutcheon's Detergents and Emulsifiers Annual", MC Publishing Corp., Ridgewood, N.J., 1981, and

Stache, H., "Tensid-Taschenbuch", Carl Henser Verlag, Munich/Vienna, 1981.

The agrochemical preparations contain as a rule 0.1 to 99% by weight, especially 0.1 to 95% by weight of active ingredient of the formula I or of an active-ingredient mixture of antidote and herbicide, 1 to 99.9% by weight, particularly 5 99.8% by weight, of a solid or liquid additive, and 0 to 25% by weight, especially 0.1 to 25% by weight, of a tenside.

Whereas commercial products are preferably in the form of concentrated compositions, the preparations employed by the end-user are as a rule diluted.

The compositions can also contain further additives, such as stabilisers, antifoaming agents, viscosity regulators, binders and adhesives, as well as fertilisers or other active substances for obtaining special effects.

For use of compounds of the formula I, or of compositions containing them, for the protection of cultivated plants against the harmful effects of herbicides of the formula II, various methods and techniques are applicable, such as those described in the following.

(i) Seed dressing

(a) Dressing of the seeds with an active ingredient of the formula I, formulated as a wettable powder, by shaking in a vessel until there is a uniform distribution over the surface of the seeds (dry dressing). The amount of active ingredient of the formula I used for this purpose is about 1 to 500 g (4 g to 2 kg of wettable powder) per 100 kg of seed.

(b) Dressing of the seeds with an emulsion concentrate of the active ingredient of the formula I according to method (a) (wet dressing).

(c) Dressing by immersion of the seed in a liquor containing 50-3200 ppm of active ingredient of the formula I for 1 to 72 hours, and optionally subsequent drying of the seed (immersion dressing).

The dressing of the seed or the treatment of the germinated young seedlings is, in accordance with nature, the preferred method of application, because the treatment with the active ingredient is directed completely at the target growth. There are used as a rule 1 g to 500 g, preferably 5 to 250 g, of antidote per 100 kg of seed; however, depending on the method of treatment, which may render possible also the addition of other active substances or micronutrients, the stated limiting concentrations may be varied upwards or downwards (repeat dressing).

(ii) Application as tank mixture

A liquid preparation of a mixture of antidote and herbicide (quantitative ratio between 10:1 and 1:100) is used, the applied amount of herbicide being 0.1 to 10 kg per hectare. This tank mixture is preferably applied before or immediately after sowing.

(iii) Application into the seed furrow

The antidote is introduced, as an emulsion concentrate, wettable powder or granulate, into the open seed furrow, and, after the covering of the seed furrow in the normal manner, the herbicide is applied before the emergence of the plants.

(iv) Controlled release of active ingredient

The active ingredient of the formula I is absorbed, in solution, onto mineral granular carriers or polymerised granulates (urea/formaldehyde), and the material is allowed to dry. A coating can if required be applied (coated granules), which enables the active ingredient to be released in controlled amounts over a specific period of time.

BIOLOGICAL EXAMPLES Test description

Seeds of the plants to be tested are sown in plastic pots each containing 0.5 liter of soil in a greenhouse. When the plants have reached the 2- to 3-leaf stage, a safener (antidote) of the formula I and a herbicide of the formula II are applied together as a tank mixture. The protective action of the safener is assessed in percent 21 days after application. Reference values are provided by plants treated with the herbicide alone and by completely untreated control plants. The results are summarised in the following Table 3.
